Abstract: A fitting for a pipe includes a cylindrical sleeve including at least one observation through window, a spigot disposed concentrically within the cylindrical sleeve and having an outer surface sized to fit within a proximal end of the pipe, wherein the cylindrical sleeve is movable with respect to the spigot in a proximal direction to a sealed position and a locking assembly interposed between the cylindrical sleeve and the spigot to lock the cylindrical sleeve to the spigot in the sealed position. The at least one observation through window provides a view of at least a portion of the locking assembly to determine whether the cylindrical sleeve is locked in the sealed position.
